g This invention relates to typographical composing machines, such asLinotype machines of the general organization represented in U. S.Letters Patent to O. Mergenthaler, No. 436,532,

wherein circulating matrices are released from a magazine in the orderin which they are to ap pear in print and then assembled in line, thecomposed line delivered to the face of a mold, the mold filled withmolten metal to form a type bar or slug against the matrices, and thematrices thereafter returned through a distributing mechanism to themagazine from which they started.

More particularly, the invention is applicable to machines which areequipped with hinged assembly mechanisms of the type shown and describedin the pending application of L. Rossetto et 2.1., Serial No. 184,072,filed September 9, 1950, where practically the entire matrix assemblingmechanism is mounted in a hinged supporting frame which may be swungfrom and to its operative position at will, not only to give access tothe interior parts of the mechanism, but also to give complete access toan auxiliary reed supporting frame which, as disclosed in saidapplication, is detachably connected to the fixed machine frame so thatthe entire bank of reeds'may be removed as a unit. 1

. Sincethe' line resistant finger against which the matrices arecomposed in the assembler elevator is slidably mounted in the hingedsupporting frame for the swinging assembling mechanism, the assemblerelevator must first be raised to remove it from the path-of travel ofthe lineresistantfinger before the frame is swung toinoperativeposition. Toward this end, means areprovided to prevent the unlocking ofthe hinged supporting-frame when the assembler elevator is in thecomposing position and, in addition, to" support the-assembler elevatorin its raised posi--. tion after the frame has been unlocked and swung:

from its operative position.

If at the time the hinged supporting frame is swung from its operativeposition any matrices should be lodged between the discharge end of themagazine and the top of the frame, damage to the matrices or to themachine parts would be apt to occur. Hence, further means are providedto prevent the unlocking of the supporting frame swinging frame is open,the matrix feeler is main-5 tamed its blocking position across... thedis-:

Claims. (01. 199-18) These and other improvements will be brought out inthe drawings and in the description following; and for a completeunderstanding of the machine to which the present improvements areparticularly applicable, reference may the above cited application.

Referring to the drawings:

be had to Fig. l is a front elevation of the hinged assem bler frame asmounted in the machine;

Fig. 2 is a perspective view of the locking de vice for thehinged'assembler frame and the safety mechanismassociated therewith;

Fig. 3 is an edge view of the locking block atcross section, toillustratethe operation of one of the safety devices; a v a r Fig. 6 isa right side elevation of the parts shown in Fig. 2; Fig. 7 is a frontelevational section taken along the line 1-1 of Fig. 6; Fig. 8 is a leftside view of parts shown in Fig. 7; and v Fig. 9 is a right sideelevation of a portion of the machine to which the present invention isapplicable, showing the matrix feeler and its manner of operation. l

The matrices areindividually released from a magazine A and fall bygravity into the vertically disposed assembler entrance comprising, asusual, 2. back plate I, a hinged front plate (not shown) andintermediate partition plates 2 providing vertical channels for guidingthe matrices in-their fall. As the matrices issue from the entrancechannels, they pass onto the upper stretch of an inclined continuouslymoving belt 3, passing around a lower driving pulley 4 and an upperidler pulley 5, whereupon they pass through and are discharged by aguide chute 6 in front of a continuously rotating star wheel 1 whichstacks them, one by one, in line in an assembler elevator B against ayielding line resistant finger 8. When the line of composed matrices hasbeen completed, the assembler B iselevated and'the' composed linetransferred to casting position.

The line resistant 8 is carried by a long slide r 9 which is provided,asusual, with an adjustable stop l0 set to control the length of line tobe composed; anda brake 'I l, cooperating with the slide 9, servestoprevent retrograde movement of the slide until the composition of theline is comstraighten up the matrices, particularly the last matrix,preparatory to the raising of the assembler elevator. When the assembleris raised and the brake II released, the line resistant is returned torightward position in readiness for the composition of the next line assoon as the assembler is returnedtoline receiving position.

All of the assembling elements thus far. described and denoted byreference numerals are mounted upon and carried by a supporting frame;

I3 which is hinged at the rightto the. fixed machine frame C, as at M,for a forward and rar ward swinging movement. By.- b:eing.-so.:mountedin the frame I3, these and otherrelementsof the assembling mechanismmaybe swungfrom. and.

to operative position at will, not only to give access to the interiorparts of such mechanism,

but also to give complete access to a removable:

frame in which the escapement reeds are mounted as abank; Inthisconnection, it -should be noted that the line resistant. 8, which.also is mounted on the swinging frame I3, is normally operative withinthe confines of theassembler B when the latter is in lowermost or linereceiving position and, hence, the; assembler. should be raised highenough to; clear the lineresistant before the frame is-swungopen.

The swinging frame 13 is heldin closedposition by means of a "rotarylocking pawl I5 (see Fig. 4)-radiating from a shor-tfore and a ftshaftI6 which is operable by ahandle l-l. conveniently located at the frontof themachi-ne- The shaft [6 is rotatably supportedrin the fixed-faceplate H) of themachinefr-ame and is given additional support byadownwardly dependingaarm H] which is attached to the front of the faceplate.

The matrix feeler operating mechanism is described inconsiderable detail in the aforementioned application, and consequentlyonly as much of that mechanism as is absolutely necessary for a completeunderstanding of the present invention is shown inthe drawings. As bestshown in Fig. 8, the matrix feeler. bar 25, which is arranged to bemoved across the lower or discharge end of the active magazine A todetect thepresenceof matrices protruding therefrom, is'operate'd from ahand lever 26 located at the front right hand'sideof the machine.

In relocking the swinging frame E3, the operation ofthe parts is simply reversed, the latch 22, when the pawl l5 fullyreenters the slotted block 2|, being pivoted from its elevatorsupporting position and permitting the latter to fall by gravity to theline receiving position.
